  description: >-
    The Solya POS backend HTTP surface. Every documented operation is
    agent-ready: it carries an `operationId`, an agent-facing `description`, the
    `pos.*` scopes it enforces (`x-required-permissions`) and an `x-agent-tier`.
    Success responses return the payload as raw JSON; failures return the
    `ErrorResponse` envelope (`{ error: { code, message, statusCode } }`).
